I bought this after having my son his nose tends to dry out and bleed in the winter. I used it a few times and put it away until this winter and when I filled it up and started using it again, it's not working. It blows cool air and even though it says you can't see the mist I know it's not working because I have had the same water in it for months now without having to refill it. So basically it was a decently expensive fan. I don't recommend buying this product.
